CONTENTS

PREFACE

What is the Primary Value Proposition for This Book?

This book endeavors to cover basic features of Angular 4, along with a variety of code samples (based on a production release of Angular 4) that will fit in a 300-page book. The primary goal of the code samples is to show you how to accomplish various tasks, such as displaying and updating a list of users, saving information to a data store, working with Observables , developing mobile applications, and so forth. If you are interested in reading Angular code samples that get stuff done, even though some details are omitted, this book might be a reasonably good fit for you.

If you are undecided about the style of this book, or if you feel that a pocket primer ought to have a different format (and opinions do vary on this point), then perhaps a different book would be more suitable for your needs.

Is Knowledge of Angular Required for This Book?

No prior knowledge of Angular is required in order to read this book. You do need an understanding of HTML (how to use basic elements) and some knowledge of JavaScript. contains code samples that combine Angular with Redux and GraphQL, which are more advanced topics. However, these two chapters can be omitted if you want to focus on core concepts in Angular. If you encounter concepts that are unfamiliar, in many cases you can learn them by reading one of the many online tutorials that explain those concepts.

Please keep in mind that there is always a trade-off between the depth and breadth of the explanation of the technical details of the code samples, as well as the type (and number) of samples to include in a short book. This book is inclined toward breadth rather than depth vis--vis the code samples. Consequently, some topics (such as testing) have been omitted, and other topics (ES6 and TypeScript) are barely covered, on an as-needed basis at best. As a result, sometimes you need to look elsewhere for more detailed information about the technical bits in the code samples, such as the ES6 methods map() and filter(), or an in-depth explanation of Observables and Promises.

If you want to be sure that you can grasp the material in this book, glance through some of the code samples to get an idea of how much is familiar to you and how much is new for you.

The Target Audience

This book is intended to reach an international audience of readers with highly diverse backgrounds in various age groups. While many readers know how to read English, their native spoken language is not English (which could be their second, third, or even fourth language). Consequently, this book uses standard English rather than colloquial expressions that might be confusing to those readers. As you know, many people learn by different types of imitation, which includes reading, writing, or hearing new material (yes, some basic videos are also available). This book takes these points into consideration in order to provide a comfortable and meaningful learning experience for the intended readers.
